golang连接etcd，测试代码

1. 安装etcd客户端

go get go.etcd.io/etcd/clientv3     
# 修复
go get -u -x google.golang.org/grpc@v1.26.0

2. 连接etcd。

package main

import (
	"fmt"
	"go.etcd.io/etcd/clientv3"
	"time"
)

// go连接etcd
func main() {
	cli, err := clientv3.New(clientv3.Config{
		Endpoints:   []string{"127.0.0.1:2379"},
		DialTimeout: time.Second * 5,
	})
	if err != nil {
		fmt.Printf("connect to etcd failed, err:%v", err)
		return
	}
	fmt.Printf("etcd boot success.")
	defer cli.Close()
}
